Box Plots and Data Analysis

The video tutorial covers lesson 16, focusing on data analysis through activities involving puppy weights and eye blinks. It guides students in creating dot plots and box plots, emphasizing the importance of the five-number summary. The lesson concludes with a review and grading of practice problems, reinforcing the concepts taught.
